help me please, I'm just stuck :(

Hello guys, need your help, I just owned a f180l, which was converted to e975. That was working good, I don't know what was in my mind, I unlocked my bootloder by freegee and installed TWRP and flash cm11 which was meant to be for e975 (int.), just screwed with baseband.
Then I had to flash f180l's F180L30c_00 rom, backup EPS by freegee, then flash e975 E97520A_00 rom, but like this tutorial: http://xdaforums.com/showthread.php?t=2792877 , I couldn't backup my IMEI, so I flash twrp with freegee again and flash f180l's kitkat baseband.

Its totally ok for then, I was using it and when battery 15% remaining phone goes off, I tried to switched on but it didn't on. Later I tried to go into recovery, 1st time and only once it went to TWRP recovery and it was showing 9% charge remaining in TWRP. I thought for low battery it doesn't on, so I select power off and plugged it for charging. On notification, it shows now red is always on and green is blinking also. I don't know it is charging or not.
I tried to go into recovery mode from fastboot, it never goes, even sometimes fastboot also goes off.
Tried to go into download mode, no luck.
when tried to switch on, it shows 'Google' logo with unlock sign at the bottom and sometimes show LG sign, then goes black or sometimes don't show LG sign, just go black.
should I go with teenybins? I don't want to get worse my situation more.
Please help me guys, I just bought it 2 days before... :(

Unlocked & relocked with freegee ...

HI dears
I've Unlcoked my OG E975 Int using freegee :( (Now I've understand what a horrible thing I've done!!!)& when I found out that the phone is not charging while off & just boots on when connecting charger (?) ,I thought maybe using classic method may help so first I RESTORED EFS BACKUPS & THEN RELOCKED BY FREEGEE! said successful !!! but after restarting I got SECURE BOOTING ERROR in the first "LG" logo!(not google),so means I couldnt use classic mode!which I DONT want to use! NEVER
SO now I must be on stock but I cant charge the phone again cause this time I have the secure booting error with"LG" logo, .
as I mentioned I have restored everything! why secure booting error? &...

Question: IF I FLASH THE KDZ NOW, WITH RElOCKED BOOTLOADER & SECURITY ERROR,
WILL THIS FIX THE PHONE (Problem of security)?
PLZ I'M in hurry, phone had only 70 percents charge!
If I dont act soon, maybe phone discharges enought to be risky to use download mode!
so will flashing fix my phone???
I've almost red all the threads about softbricks! I want to RESTORE TO STOCK! I AM ON STOCK! teeny bin will give me unlocked boot loader which I DONT want! do I have to pass all the steps you've mentioned or just flashing KDZ?(teenybin,cm,...)
any help i'm confused! thanks

I will try flashing...

Hey body your last situation has given me some hope!
Im gonna flash tomorrow & see if the security problem can be solved!
just stay a while! plus I said I restored EFS & relocked!
if you want to relock with freegee, try this:
FIRST CHARGE YOUR phone 100%! you cant when you get security problem...
then relock & after relock, restore efs backups - copy the backups in pc first
you know I guess you will get the security problem again!
but at least you have fully charged phone!!
not 50% like me.... :crying:
Im gonna give my OG e975 to some repairer to flash! my pc is terrible!
so I'll give you guys the result...
hope flashing will fix...:confused:
also I got the 4.4.2 KDZ (970) MB by giving the S/N to some lg site! that was so easy!!downloaded with ADM!
no one told me, is 50% charge enough for flashing or not???

Flashed! security problem solved! unrooted! 4.1.2 again!

hey guys!
I have some good advice for you:p
I unlocked & relocked with freegee & faced secure booting error.
so today I gave my phone for flashing to an experienced guy.
yeah! every things gooood! problem of security solved!charging while off solved!
& The good advice:
Don't take any risk by flashing them with that flash tools!(in freegee problem at least)
believe me 5$ is not that much worthy even against the "possibility" of bricking!
Im proud to be coward for flashing in booting problem!
your only hope is download mode! what if you lose it?
You need to hold volume down & connect usb for download mode?
So try flashing with box! yeah! that guy connected the box to pc & phone to the box!
Just the time he connected the usb to device, it went to download mode automatically with no button!
it seems even the phone likes the box usb more than pc usb!
also no need to open the device! Thats for unbrick I guess.

in 10 minutes & 0%(maybe) possibility of bricking, the phone flashed & started up!
no S/N changing! because I restored the EFS I think(not sure).
no flash tool softs! He is flashing all sami,sony,lg,htc etc with an special app named octopus .box was Dlink.

believe me there are better options than that kdz updater etc...
Anyway try whatever you want! I just described what I did, as I promised!
now I've got the little OTA updates of 4.1.2 & gonna root it & install xposed & enjoy it!
dont want to get 4.4.2! I wanna enjoy Eco Mode! & Dalvik with xposed!:eek:
maybe unlocking with first method later...

Hey yogivin
thanks for any guide you've gave to me!
Also actually I thought India is at least better than here! I 've paid 3 times more in our money! just converted our money to dollar! also sorry for eng problems...
I didnt trust that guy at first! I had made my choice to flash it myself this afternoon, when I saw an idiot one! but after a little searching I found who I wanted to flash! I had to go to some nearby cities to find an experienced one! He is flashing a phone per half an hour daily! I was shocked!
anyway Im so much thankful to you & anyone who wrote his comment!:fingers-crossed:
hope no one bricks his phone because thats such a really really bad pain!

has anyone tried the first method?
Im going to try it ,hope I will not softbrick my device or sth else...

So yeah! First method is freegee too! But I can't say you won't be able to flash after that! I was able to flash again without relocking.but after unlock you'll lose wifi.
Now I'm just fine with a comfortable mind! No other ways for unlock which I didn't try!

Found some perfect modules for those who want to restore to stock(4.1.2):

    [Guide]Restore to Stock "Bricked" "Unlocked" LG Optimus G f180,E97x

    The problem starts when you unlock F180 Bootloader with "freegee":

    Unlock the bootloader
    :

    There are 2 ways:
    Method 1: Unlock the bootloader
    http://www.mediafire.com/download/kzbp2gicuj22cv5/Tool_Root_Unlock_BL_4.1.2_edited.zip
    Advantages:
    - enough fastboot functions: Start, Power Off, Recovery mod, Restart Bootloader
    - Easy on the function keys
    -Cons:
    - To Relock, just you have to flash KDZ

    Method 2: Unlock by app
    https://play.google.com/store/apps/details?id=edu.shell.freegee_free&hl=en
    Advantages:
    - Add.
    - Can be easily Relock by app.
    Cons:
    - Right to Recovery through app (on Stock Rom & 975).
    - Loss of function fastboot that this very important function.
    - When crashes, not able to Recovery by pressing hard.

    It is recommended to use the first way. :angel:
    on E975, E970, E97.x unlock, select KT or SKT. Because E975 and the S / K has Same bootloader unlock.

    i have already faced this situation to unlock bootloader with freegee and stuck with google logo and fastboot mode :crying:

    not even KDZ flash working, always result in fastboot or KDZ tool stop working. also tried different KDZ and flashing Tools

    Tried "TeenyBin" ,not success :crying: but get twrp working, then flash CM10 as suggested but got this

    Subsystem Crash!
    ------------------------------------------------------------
    DemiGod Crash Handler : Subsystem Crash! : External_modem (Undefined error)

    Press key to choose Dload Mode/Reboot/Fastboot.
    1) Volume Up : Dload Mode.
    2) Volume Down : Reboot.
    3) Power : Fastboot.

    ------------------------------------------------------------

    to solve this have to remove sim card and change baseband in TWRP using ADB
    then perform a hardreset.

    now the device comes in life again :)

    but you find the device is not properly working may be sim or gprs or wifi or something else.

    now have to unlock bootloader again by adb with this method

    Method 1: Unlock the bootloader
    http://www.mediafire.com/download/kzbp2gicuj22cv5/Tool_Root_Unlock_BL_4.1.2_edited.zip
    Advantages:
    - fastboot functions: Start, Power Off, Recovery mod, Restart Bootloader
    - Easy on the function
    -Cons:
    - To Relock, you have to flashed KDZ
    after that will able to flash the stock KDZ without any problem :)

    put device in D/W mode and flash it with appropriate official KDZ
    Guide to flash KDZ
    http://xdaforums.com/showthread.php?t=2388440
    :good:

    have to follow the procedure because adb in recovery not able to replace the bootloader files

    KDZ flash After mako bootloader unlock

    step 1:
    use TeenyBin http://xdaforums.com/showthread.php?t=2249500
    get twrp working, then flash CM10 for you device.

    you will got this
    Subsystem Crash!
    ------------------------------------------------------------
    DemiGod Crash Handler : Subsystem Crash! : External_modem (Undefined error)

    Press key to choose Dload Mode/Reboot/Fastboot.
    1) Volume Up : Dload Mode.
    2) Volume Down : Reboot.
    3) Power : Fastboot.

    ------------------------------------------------------------

    step 2:
    to solve this have to remove sim card and change baseband in TWRP using ADB
    then perform a hardreset.

    to reflash the bootloader files you have to enter in CM10 or some ROM with SU or busybox;


    now the device comes in life in CM10
    now the device comes in life again

    but you find the device is not properly working may be sim or gprs or wifi or something else.

    now have to unlock bootloader again by adb with this method

    Can you also add the step by step procedure to unlock bootloader using the first method? As in wether your phone should be in download mode, charge only mode etc etc.

    enable usb debugging
    connect as MTP
    follow the script ;)

    Hey
    Yesterday I flash CM11 over stock 4.1.2 on my Optimus G (E975) and later decided to go back to stock again.
    Everything was done witouht problems using nand back up with CWM
    But later I realiced that M5 was out and, once again tried to install it but I couldnt

    Dont know what happen but now while device is turning on, or trying to go into recovery or dowload mode screen is BLACk.
    Device is working properly, I mean I turn it off/on and no problem. Just cant enter fastboot, recovery or download mode.

    I tried a couple method to go back to stock using KDZ but proceess stop and nothing, just keep pressing power buttom and phone reboot (just black screen during the process)

    Please, any ideas/suggestions


    O no please.
    I follow method one, I get succes message and now my wifi refuses to turn on. WTF

    Update 2:
    Now Im screwed. I tried to install another recover with Rom Manager and now phone refuses to turn on.
    Something is detected in the pc while conecting it but I have only a black screen

    Please what can I do??

    have you tried TeenyBin http://xdaforums.com/showthread.php?t=2249500

    Yes but I could solve that problem now.

    One thing I learned: I will never install a custom rom on my OG. I had several devices before this one and always with custom roms. But with LG there are so many risks and problems to perform needed actions

    Thanks

    very true. iv learned the lesson too..it was risky to install stock back
    its not a cheap phone after all..moreover stock roms are the best ones. u wont get those features n qlides etc in custom
